Authentication

Open Source Auth
(with tons of integrations)

Every Supabase project comes with a complete User Management system that works without any additional tools.

Including PostgreSQL's policy engine, for fine-grained access rules.

All the social providers

Enable social logins with the click of a button. Google, Facebook, GitHub, Azure, Gitlab, Twitter, Discord, and many more.

Fully integrated

Incredibly simple Auth, without a single external authentication service. Built-in Authentication, Authorization, and User Management.

Own your data

User data stored in your Supabase database so you never have to worry about 3rd party privacy issues. Host your data in 8 different locations.

Simple APIs

APIs that you can understand. With powerful libraries that work on client and server-side applications.

Enterprise logins

Support for SAML, Azure. More enterprise providers and SSO coming soon.

Social login scopes

Request additional user data permissions when using social logins.


  // Sign up with email
  const { user, error } = await supabase.auth.signUpWithPassword({
    email: 'example@email.com',
    password: 'example-password',
  })


  // Sign in with email
  const { user, error } = await supabase.auth.signIn({
    email: 'example@email.com',
    password: 'example-password',
  })


  // Sign in with magic links
  const { user, error } = await supabase.auth.signIn({
    email: 'example@email.com'
  })


  // Sign in with GitHub
  // And request extra permissions!
  const { user, error } = await supabase.auth.signIn({
    provider: 'github',
  }, {
    scopes: 'repo gist notifications'
  })

User permissions without the middleware

Supabase Auth works without any additional servers. Build Authorization rules with Postgres' Row Level Security, controlling who can create, edit and delete specific rows in your database.

Policies can be written in SQL or using the dashboard online.

-- 1. Create table
create table profiles (
  id serial primary key,
  name text
);

-- 2. Enable RLS
alter table profiles enable row level security;

-- 3. Create Policy
create policy "Public profiles are viewable by everyone." 
on profiles for select 
using ( true );

-- 1. Create table
create table profiles (
  id serial primary key,
  name text
);

-- 2. Enable RLS
alter table profiles enable row level security;

-- 3. Create Policy
create policy "Users can update their own profiles." 
on profiles for update 
using ( auth.uid() = id );

create table teams (
  id serial primary key,
  name text
);

create table members (
  team_id references team.id,
  user_id referenced auth.users.id
);

alter table teams enable row level security;

-- Create Advanced Policies
create policy "Team members can update team details"
on teams
for update using (
  auth.uid() in ( 
    select user_id from members 
    where team_id = id 
  )
);
